If you wish to make a web site, you need two things - your own domain and a hosting plan for it. The domain registration is the actual website address that you type in a web browser to access a site, while the hosting space is where your site files is going to be. These are two very closely connected, yet separate services, while many people assume that registering the domain is enough. Similar to the disk space and the monthly traffic features that a given web hosting plan offers, there are a certain number of registered domains you can include as hosted i.e. you can have the web content for them in some account even when the domains have been registered using a different company. In technical terms, it does not matter if a domain name is registered and hosted with the exact same company or is registered with one company and pointed to another - either way your websites will operate the very same way.
